Is thîs for the Roman rite or the Ambrosian rite? If you happen to attend a Mass in Milan there is an extremely high chance that it will be in the Ambrosian rite and not the Roman rite that most of us are acquainted with. I ask because if you are going to be in Milan then you are going to need a different set of liturgical books than for the Roman rite as well, as they use a different lectionary, liturgical calendar, & cetera. The books for the Ambrosian Rite are even harder to come by and most of the Milanese do not even take pride in their liturgical patrimony so they may not be of any assistance once on the ground if you are going to be there.
